Donaldson Ultraporex B prefilter element is designed for removal of particulate contaminants in gases. Ultraporex B utilize a highly porus sintered media for absolute filtration of particles down to 25 µm in size. Although the Ultraporex B is primarily used as a particulate prefilter, a simple reversal of flow through the element allows the Ultraporex B to be used as an effective course coalescing filter element, removing bulk quantities of water and oil from an air or gas stream.
Donaldson Ultraporex B prefilter elements utilize a highly porus sintered media for absolute filtration of particles down to 25 µm in size. The primary filtration mechanism of this media is sieving, which captures most particles near the surface allowing for regeneration of the element and reduced operating cost through fewer element change-outs. Although the Ultraporex B is primarily used as a particulate prefilter, a simple reversal of flow through the element allows the Ultraporex B to be used as an effective course coalescing filter element, removing bulk quantities of water and oil from an air or gas stream (standard housings are equipped with an internal float drain, so no special equipment is required).
The high-grade sintered bronze media ensures not only a high load capacity of contaminants, but also long life through its resistance to aggressive condensates and its ability to be regenerated many times.
